Full title- A COMPARISON OF THE INHIBITORY EFFECTS OF METAL IONS

Enzymes are an essential part for the functioning of the human system. Most of the enzymes require binding of metal ions and other non-protein components for their appropriate functioning. Such non proteins, which facilitate the functioning of enzymes, are called cofactors. The cofactors can be an organic cofactor as Thymine Pyrophosphate (TPP), Flavin Adenine Dinucleotide (FAD), Nicotinamide Adenine dinucleotide (NAD); or inorganic cofactors like metal ions, Mg2+, Cu2+, Mn2+, Zn2+ and Iron-sulphur clusters. When the enzyme is bound to a cofactor, ready to carry out its function, it is known as a ‘Holoenzyme.' An enzyme without a ...

1.Jupiter was the first. Giant lies just beyond the frost line. As the frost line accumulated great amounts of water via evaporation from infalling icy material, it created a zone of lower pressure that increased the speed of orbiting dust particles and halted their motion toward the Sun. As a result , the frost line acted as a barrier whice lead material to accumulate. This excess material coalesced into a huge embryo of around 10 Earth masses, which then began to grow rapidly by swallowing hydrogen from the surrounding disc, reaching 150 Earth masses in only another 1000 years and finally topping out at ...
